带电粒子在电、磁场中的运动是一个较复杂的综合性物理问题.物理高考说明中把带电粒子在电磁场中的运动作为重要知识点.纵览几年高考物理试题,也是把它列为考核的重点,这就要求学生熟练掌握这部分知识,并能综合运用它们解决实际问题.现就如何解决这方面的问题谈几点看法. The movement of charged particles in electric and magnetic fields is a more complex comprehensive physical problem. The physical entrance examination shows that the movement of charged particles in electromagnetic fields is an important knowledge point. A review of the physical examination questions in college entrance examinations for several years is also listed as an assessment. Focus, this requires students to master this part of knowledge, and can use them comprehensively to solve practical problems. Now on how to solve this problem in a few points.
